A reticle includes a first pattern formed in a first die flash region of the reticle and a second pattern different than the first pattern formed in a second die flash region of the reticle. A method for patterning a wafer having a plurality of die regions defined thereon includes exposing a first die region using a first pattern formed on a reticle during a first exposure, repositioning the reticle, and exposing the first die region using a second pattern formed on the reticle during a second exposure.
